when we feel sleepy, our body systems start working slowly so as they become slower the body receives less oxygen due to slowing down of the respiration, therefore, in order to take in oxygen in the required amount back into the body we stretch up.... u might have experienced that after stretching we yawn... this is the reason..... i hope u understand......
